A collection of classical works on space flight, published prior to 1932, is presented. Rocket motion, interplanetary flight and planetary landings, flights to the moon, astronaut intravehicular and extravehicular activity, and rocket sounding of the upper atmosphere are covered. The authors include Robert Esnault-Pelterie, Robert Goddard, Hermann Oberth, Walter Homann, Hans Lorenz, A. Shershevskii, and Julius Kuntz. It is pointed out that different people in different countries independently came to the conclusion that interplanetary travel was feasible but impracticable at that time because of technical and financial difficulties.
